Answer:

x = 12

Step-by-step explanation:

18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.

Using this 3:4 scale factor we can find the missing side x.

Solving for x :

[tex]\frac{3}{4}[/tex] × 16 = 12

x = 12

OR: Set up a proportion:

[tex]\frac{24}{16}[/tex] × [tex]\frac{18}{x}[/tex]

cross-multiply

16 × 18 = 288

24 × x = 24x

288 = 24x

x = 12

Step-by-step explanation: set the two equations equal to each other. 5-2x=-4x+9 and you'd get x=2. insert 2 into the expression, and you'd get 1. to find the perimeter, a triangle has 3 sides. 1+1+1 =3

Based on the information given, it should be noted that the value of 1260 will therefore be £73.09.

From the information given, it was stated that £29 =500. Therefore, the equation to solve that of 1260 will go thus:

£29 =500

£1 = 500/29

£1 = 17.24

Therefore, 1260 will be:

= 1260/17.24

= £73.09

Answer:

Number of sent mail = 36

Number of received mail = 75

Step-by-step explanation:

Let,

x be the number of mails sent

y be the number of mails received

According to given statement;

x + y = 111      Eqn 1

y = 2x + 3     Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x + 2x + 3 = 111

3x = 111 - 3

3x = 108

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{108}{3}\\x = 36[/tex]

Putting x = 36 in Eqn 2

y = 2(36) + 3

y = 72 + 3 = 75

Hence,

Number of sent mail = 36

Number of received mail = 75

Step-by-step explanation:

Since you want to find the variable x all you have to do is simple subtraction.

The two numbers (61 and 22). Subtract those numbers and you get 39. Now it wants you to round to the jearest hundredth but there is no hundreds place so we can round to the nearest tenth. Which would be 30! Hope it helped... :)!

Answer:

E. (7,-2)

Step-by-step explanation:

Answer: 1719.22 mi squared

Step-by-step explanation:

you have to find the height first.

you only have r and hypotenuse

so

a^2 + b^2 = c^2

13^2 + b^2 = 29.1^2

169 + b^2 = 846.81

b^2 = 846.81 - 169

b^2 = 677.81

b = 26.03

height = 26.03

surface area formula :

          _______

πr(r+_/h^2+r^2)

                   ___________

π(13) [13 + _/26.03^2 + 13^2]

= 1719.22

Answer:

y = n - 0.26n

y = 0.74n

Step-by-step explanation:

The equation that can be used to express the function above is given an Exponential Decrease function

Where:

y = a(1 - r)^t

Where

y = July sales

a = n = June sales

r = rate of decrease = 26% = 0.26

t = time in months = June to July = 1 month

t = 1

Hence, our equation =

y = n( 1 - 0.26)¹

y = n(1 - 0.26)

y = n - 0.26n

y = 0.74n

The equation that can be used to determine the sales in July is given as:

y = n - 0.26n

y = 0.74n

Answer:

  A: ∠W'Z'Y' = 60°; angles aren't changed by rotation

  B: W'(-3, 6), X'(9, 6), Y'(8, 1), Z'(-4, 1)

Step-by-step explanation:

Part A:

Angle WZY is the supplement of the given angle ZWX, so is ...

  ∠WZY = 180° -120° = 60°

Rotation about the origin (or anywhere else) does not change angles. The new parallelogram will have ...

  ∠W'Z'Y' = 60°

__

Part B:

The transformation right 2 and up 3 can be described by ...

  (x, y) ⇒ (x +2, y +3)

Then the translated vertices are ...

  W(-5, 3) ⇒ W'(-3, 6)

  X(7, 3) ⇒ X'(9, 6)

  Y(6, -2) ⇒ Y'(8, 1)

  Z(-6, -2) ⇒ Z'(-4, 1)
